Good day,
Thank you very much for your time and patience.
Sorry for the delay.
For your case, please refer to the following suggestions:
- Where are you located?
- Please check if the network type of the sim card is included by M7350:
4G: FDD-LTE B1/B3/B7/B8/B20 (2100/1800/2600/900/800MHz)
3G: DC-HSPA+/HSPA/UMTS B1/B8 (2100/900MHz)
2G: EDGE/GPRS/GSM Quad Band (850/900/1800/1900MHz)
- What is the internet IP address on the basic>network map, is it 0.0.0.0?

- If the sim card is put into the mobile phone, are you able to get internet service on the smartphone?
---if yes, could you please check the APN info and manually create the same APN profile on the M7350;

Thanks a lot.
